hedena_gold/apps/user-app/src/components/product/CartItem.vue

<!--
  Cart line item, restyled into the redesigned design language (see
  components/home/* and HomeView): LESS colour tokens, BEM class names,
  hairline borders, wine accent.

  Ported originally from legacy henza_pwa/src/components/product/cartItem.vue.
  Dropped there and still absent: the "اجرت ریالی" (Rial wage) block, which
  displayed `selectedVariant.rial_pay` — no such per-variant Rial field exists
  anywhere in our domain model, so there is nothing honest to show.

  All cart behaviour is unchanged: quantity increment/decrement, remove at
  qty 1, and the note affordance that opens the parent's drawer.
